This invention relates to lifting and handling equipment, in particular, to load handling devices.

The aim of the invention is to increase the reliability of operation.

Figure 1 and 2 shows the load-lifting device, a General view.

The load gripping device includes a housing 1, two shoulders gripping fish JQ acts on the rod

Working medium with sliding wedge drives the levers 2, clamping reliably grips

chaga 2, spacer wedge 3 and air cylinder 4, which is its drive.

Case 1 with its cavity is rigidly fixed with pins 5 on the case of the power cylinder A.

The housing 1 from one end 6 is cylindrical with a cavity, and its second end contains two parallel flat guide posts 7.

Two shoulders gripping levers 2 are made with shoulders inclined towards each other at an obtuse angle. On one shoulders, there are fixed oval lips 8 with a wavy, rough working surface, and on the other shoulders, rollers 9.

Two shoulders levers 2 at the junction of their shoulders by means of horizontal axes 10 are fixed among the paral-. of flat racks 7 of the housing 1.

An expansion wedge 3, flatly formed and rigidly fixed on the rod 11 of the power cylinder 4, can be moved among the parallel guide plates of the flat struts 7 along the support rollers 9.

The spacer wedge 3 is provided with angle levers 12, hinged with their corners on the flat side surfaces of the spacer wedge 3, on each shoulder of which the rollers 13 are mounted at the ends.

Load handling device operates as follows.

Formula and

The load gripping housing, closed horizontal axle levers, shoulders to each other under the clamping jaws, placed between the drive and the front and rear legs, and the lever lock lever, distinguish that, for the purpose of working, the lock lever lever from the hinge, hingedly, one by one on the surfaces by the arrangement of the openings of the shoulders with the gripping p ends to the clamping ends of the ends in pairs for contact with the vertical with the sides of the shoulder levers.

The working medium moves the rod 11 with a wedge 3, which actuates two shoulders gripping levers 2, while the clamping jaws 8 securely hold the load.
